Opaque-2 corn contains approximately 50 to 100% more lysine and 50% more tryptophan than normal corn varieties. Since these two amino acids are the most deficient normal corn varieties. Since these two amino acids are the most deficient in normal corn-supplement rations, the sue of opaque-2 corn in swine diets will reduce the amount of protein supplement needed. Previous research at South Dakota has shown that finishing pigs fed opaque-2 corn supplemented with lysine and threonine grew at a similar rate but required more feed/gain than pigs fed a 13% protein corn-soybean meal diet. The objective of this study was to determine the value of adding the amino acids, lysine, isoleucine and threonine to opaque-2 corn diets for finishing swine.
